Flutter软件包获取未安装新软件包 [英] Flutter packages get does not install new package

问题描述

我正在尝试在flutter中安装软件包(dynamic_theme).当我运行flutter packages get -v时，它甚至都没有尝试安装该软件包.

I'm trying to install a package (dynamic_theme) in flutter. When I run flutter packages get -v it does not even try to install the package.

到目前为止，我已经尝试过:

So far I've tried:

• 运行flutter packages get
• 运行flutter packages get
• 重新启动计算机
• 更新的抖动
• 添加了另一个软件包，但没有安装
• 更新的Android Studio

• Running flutter packages get
• Running flutter packages get
• Restarting my computer
• Updated flutter
• Added another package but that did not install either
• Updated Android Studio

在我的pubspec.yaml中，输入:

In my pubspec.yaml I've put:

dependencies:
  flutter:
    sdk: flutter
  firebase_core:
  cupertino_icons: ^0.1.2
  dynamic_theme: ^1.0.1 # the package does not install
  uuid: 2.0.0 # the package does not install

在flutter packages get的详细运行日志中，它将安装输出的软件包:

In the logs for the verbose run of flutter packages get where it installs the packages it outputs:

[ +422 ms] Running "flutter packages get" in quiz_app... (completed in 0.4s)
[  +57 ms] Found plugin firebase_core at E:\Other\SDKs\flutter\.pub-cache\hosted\pub.dartlang.org\firebase_core-0.3.4\
[  +13 ms] Found plugin shared_preferences at E:\Other\SDKs\flutter\.pub-cache\hosted\pub.dartlang.org\shared_preferences-0.5.2\

[  +26 ms] "flutter get" took 718ms.

我希望flutter下载并安装了这些软件包，但它只是检查是否已安装的软件包(例如firebase_core)上的更新.

I expected that flutter downloaded and installed the packages, but it does just check for updates on the already installed packages like firebase_core.

推荐答案

有些事情是随机解决的.我什么也没做，只是尝试了多次.尝试10次后，它下载并安装了uuid和dynamic_theme.

Something solved it randomly. I did not do anything but try multiple times. After some 10 attempts it downloaded and installed both uuid and dynamic_theme.
